摘要: In this paper, electrochemical test-data were obtained from 0.5 M H2SO4-immersed steel-reinforced concrete admixed with different Rhizophora mangle L bark-extract concentrations and subjected to modelling analyses for studying corrosion-inhibition effectiveness. For this, macrocell current zero-resistance ammeter corrosion-rate linear-polarization resistance instruments respectively total-corrosion as per ASTM G109–99a statistical-distribution G16–95 R04. Further of these modelled test-results showed that the correlated excellently (R = 95.04%, Nash-Sutcliffe efficiency 90.33%, p-value 0.037) function concentration samples. agreements, both experimental correlation fitting models identified 0.167% barkextract good efficiency, η 73.30% (experimental) or 60.81% (correlation prediction). These bare implications on technique usage complimenting identification admixture effective steel-rebar in microbial/industrial simulating-environment studied.
